Description
Summary:Pineapple (Ananas comosus), is a tropical fruit of South American origin, it is favorable for humans due to its bromelain content, it has favorable potential for the recovery of weight loss, it is rich in vitamins A, B, C and E. ; It has minerals like phosphorous, calcium, magnesium, iron and copper. Pineapple is the most demanded fruit in the world, due to its pleasant flavor and high fiber content. It has a high percentage of water, it is low in calories. Pineapple stems contain bromelain, a digestive proteolytic enzyme that acts as a substitute for gastric juices, improves digestion and destroys intestinal parasites. It is also used in the food industry, as a meat tenderizer. The main insect pest of pineapple cultivation is the mealybug Dysmicoccus brevipes, it can be found in all parts of the pineapple, but especially at the base of the basal leaves, the roots of the plant, and in the floral cavities of the fruit. Mealybugs cause yellowing in the plant and retard its growth, since they feed on the sap of roots, stems and fruits. They are vectors of the “Wilt” wilt virus. Its control is very difficult, since this pest attacks at any stage of crop development. Constant monitoring must be maintained, the presence of mealybugs is closely related to the population of ants, which protect the mealybug from the attack of parasites, predators and keep the colony clean from the presence of fungi that can affect both the mealybug like the plant. As a chemical control, at a low incidence of said pest, insecticides can be used, such as potassium salt soap or botanical extracts. In case of high infections, it is worth using products based on diazinon, chlorpyrifos, among others recommended for the crop and plague, following the recommended dose on the label.
